Trump to Canada: Pay $61B for Golden Dome or Join U.S. as 51st State

U.S. President Donald Trump says Canada can either pay $61 billion USD to join his ambitious Golden Dome missile defense system—or join it for free by becoming the 51st U.S. state.

The offer, posted to Trump’s Truth Social account on Tuesday, is the latest twist in an increasingly dramatic security and sovereignty standoff between the two longtime allies.

“If they remain a separate, but unequal, Nation… $61B. If they become our cherished 51st State… $0,” Trump wrote.

Canada Responds: We’re Not for Sale

Prime Minister Mark Carney’s office quickly rejected the annexation idea, emphasizing that Canada remains a “sovereign nation” and is already in “constructive” talks with the U.S. about defense cooperation—including NORAD and the Golden Dome project.

This comes after Carney’s throne speech reaffirmed Canada’s independence and outlined plans to reduce its reliance on U.S. defense by joining Europe’s ReArm military initiative.

“Canadians gave the prime minister a strong mandate to negotiate a new security and economic relationship,” a spokesperson said, without addressing the $61B price tag.

What Is the Golden Dome?

Unveiled earlier this year, Golden Dome is Trump’s $175B vision of a North American space-based missile shield, modeled after Israel’s Iron Dome—but far more advanced. It would combine hundreds of satellites, sensors, and AI-driven interceptors to shoot down incoming threats from China, Russia, and rogue states.

The goal? Block missiles from space before they reach U.S. or allied soil.

While Trump wants it fully built by 2029, experts say the system could take 10–20 years and cost over $800 billion, with funding and bipartisan support far from guaranteed.

Trump’s “Annexation” Comments Reignite Tension

The post also marks the first time Trump has revived his 51st state rhetoric since a May 6 Oval Office meeting with Carney. That move comes just days after U.S. Ambassador Pete Hoekstra dismissed the annexation idea as “over.”

“If the Canadians want to keep talking about it — that’s their business. I’m not talking about it; Donald Trump is not talking about it,” Hoekstra said.

That didn’t age well.

Global Reactions: Alarm Bells Ringing

The announcement comes amid international backlash. North Korea accused Trump of pushing the world toward a “space nuclear war”, calling the Golden Dome plan an act of “arrogance” and a potential trigger for a space arms race.

China, too, issued sharp criticism last week, saying the system “undermines global strategic balance.”

Despite these warnings, Trump has charged ahead. At a recent press conference, he appointed U.S. Space Force General Michael Guetlein to lead the program and name-dropped SpaceX, Lockheed Martin, and Anduril as potential contractors.

Can Canada Afford to Say No?

While Ottawa weighs the $61B buy-in versus increasing European ties, defense insiders say the Golden Dome will impact Canadian security—whether it joins or not.

A U.S. general recently told Canadian officials that Canada is being considered for advanced sensor development, which could give Canadian companies a slice of the defense economy, but at the risk of strategic dependence on U.S. systems.

Should Canada spend billions to join Trump’s Golden Dome—or strengthen ties with Europe instead? Let us know where you stand.
